Hi Guys,

I am trying to clone a VM Template to the Same Storage, that the template is on and the following is happening:

create full clone of drive scsi0 (OS_DATA_STORE:vm-6000-disk-0)
WARNING: dos signature detected on /dev/OS_DATA_STORE/vm-100-disk-0 at offset 510. Wipe it? [y/n]: [n]
Aborted wiping of dos.
Logical volume "vm-100-disk-0" created.
1 existing signature left on the device.

Does anyone have any idea why ?

The raw images are being stored on an iSCSI Device with an LVM on top of it.

it seems someone else reported the same (or similar?) bug here: https://bugzilla.proxmox.com/show_bug.cgi?id=2377
maybe there is some information that can be provided to find the problem?
I added some information to this bug

but somehow it created a huge amount of white space in the bug comment I see no option to edit it and it is making it so readers will have to scroll through huge amounts if white space to read the rest of my comment,
